FB Marketplace, but that's about it. Even that is a hot bed for people like bike thieves.

Maybe there are more modern, advanced data structures / techniques, but yes, my understanding is that this is a common trade off (having your data structure be more static, with offline updates).

I also find Succinct Data Structures fascinating. I own Navarro's text book, and it's one of my favorite books to take to the coffee shop and try to understand. I also have a copy of Jacobson's Thesis.

Since information is rather scarce, here's my shameless plug for a related blog post I made, which includes a few links at the end to more resources https://denvaar.dev/posts/jacobsons_rank.html

One thing that helps me write is to picture someone I know who I'm talking to. This helps me to include the appropriate level of context, and it also impacts the "voice" I will use. I think the author basically mentions this as one of the their list items.

I have noticed that when people are explaining the rules of a game, they tend leave out the goal of the game, or wait to mention it toward the end of the explanation. You gotta lead with what the goal of the game is.

Yeah, I probably should just get good at pour-over. The Moccamaster is great, but I have a pretty low bar coming from a MrCoffee.

I would like to know if the plastic used in my Moccamaster is subject to these hazards. I bought it specifically because they claim to use food-grade quality plastic that is supposed to be safe.

One other thing about Lael that I don't think the article mentioned is that on top of being an amazing ultra-endurance cyclist, she also has had to deal with lots of respiratory problems. I don't remember if it's Asthma or what, but her lungs literally shut down at times. This makes it even more impressive to me.

EDIT: It's Asthma - https://youtu.be/h0hkoee6sI8?si=NaR4GZjUppQE78xm

Sadly, I have found this to be true for many things. Not dismissing any real, physical aspect, but there's always a psychological aspect that comes into play as well.

EDIT: I actually love that it's text based, even to the point of creating sigma notation out of plain text.

My view is that shell scripting feels like the wild-west, so I try to conform to POSIX to maintain some level of sanity, though it feels restrictive at times. I rely on ShellCheck to help me write shell scripts that are POSIX compliant.

The benefit of hjkl is that it keeps your fingers on home row. I see your point that it could be considered dogmatic, though. Personally, I'm a fan of hjkl.

I didn't get the impression that this post was trying to compare vim to anything (which is refreshing). Seems like this is simply demonstrating how to use vim, given a few real-world editing examples.

The gif's/short clips of each situation were a good way to present that information.
